[0037] Among them, cold water is stored in the water tank 501a, and the cold water can dissipate the heat of the motor 501b to prevent the motor 501b from increasing the heat inside the lamp housing 100; the spring push rod 501f has elastic force and can reset the extrusion block 501c after it moves, and under the action of the spring push rod 501f, the top rod 501e always slides with the concave-convex disk 501d; the wire-fixing rubber 501g is used to fix the wire. When the two pieces of wire-fixing rubber 501g are combined, while fixing the wire, it can also block the outlet of the wire, thereby forming a sealed environment inside the lamp housing 100 to facilitate ventilation of the extrusion block 501c.

[0038] The air intake member 502 includes an air intake pipe 502a, a processing pipe 502b, a filter hole 502c and an air intake hole 502d. The air intake pipe 502a is connected to the side of the lamp housing 100, the processing pipe 502b is slidably arranged on the inner wall of the air intake pipe 502a and has two chambers, the filter holes 502c are opened on both sides of the chamber where the processing pipe 502b is located inside the air intake pipe 502a, the air intake hole 502d is opened on the side of the chamber where the processing pipe 502b is located outside the air intake pipe 502a, and the interior of the chamber where the processing pipe 502b is located inside the air intake pipe 502a is filled with water-absorbing particles.

[0039] The enhancement component 503 includes a cross bar 503a, a strip hole 503b, a top ball 503c, a spring 503d, a side plate 503e and an extrusion strip 503f.

[0040] The air inlet 502 and the efficiency enhancing member 503 therein are both provided in two groups, each group includes a plurality of lamps, and the two groups are symmetrically arranged about the center line of the lamp housing 100. The side panels 503e and the extrusion strips 503f are also provided in two groups and cooperate with the efficiency enhancing member 503.

[0041] During use: In hot weather, the fin heat sink 400 dissipates heat for the LED substrate 300, and heat is gradually accumulated inside the lamp housing 100. Then the control system of the street lamp turns on the motor 501b. After the motor 501b is turned on, it drives the top rod 501e to rotate. When the top rod 501e slides on the lower surface of the concave-convex disk 501d, the extrusion block 501c is lifted up and pulled down by the spring push rod 501f. As a result, the extrusion block 501c performs repeated lifting and lowering movements, and the lamp housing 100 is in a closed state, and the air inlet 502 is the only entrance and exit.

[0042] When the extrusion block 501c falls, the hot air flow inside the lamp housing 100 is squeezed to the air inlet pipe 502a, and then flows to the outside of the lamp housing 100. When the extrusion block 501c rises, negative pressure is formed inside the lamp housing 100, and the side plate 503e drives the extrusion bar 503f to squeeze the top ball 503c, and the outside air flows into the air inlet pipe 502a, and then enters the processing tube 502b through the filter hole 502c. Since the top ball 503c is squeezed and drives the processing tube 502b to move, the cross bar 503a and the water-absorbing particles inside the processing tube 502b form a relative displacement, and the water-absorbing particles are stirred, so as to fully contact with the outside air in the air inlet pipe 502a, which can not only remove dust from this part of the air, but also absorb moisture from the outside air, thereby preventing the moisture in the air from corroding the circuit inside the lamp housing 100.

[0043] The outside air has a lower temperature than the air inside the lamp housing 100 , and can cool the LED substrate 300 . In addition, under the squeezing action of the squeezing block 501 c , the gas flow rate is accelerated, thereby improving the heat dissipation efficiency of the fins.

[0044] The remaining structures are the same as those of Example 1. Example

The fixing frame 603e is located on the outer side of the gear ring 601d and is fixedly arranged on the inner bottom of the lamp housing 100. The hose 603d is fixedly arranged on one side of the fixing frame 603e close to the gear ring 601d.

[0049] Among them, the auxiliary radiator 603a has no fan part, and its fins are columnar, which is more in line with gas flow. Its function is to dissipate heat for the water in the water tank 501a; the connection port of cooling pipe 1 603b and water tank 501a is lower than the connection port of cooling pipe 2 603c and water tank 501a, and the flow direction of cooling water is water tank 501a—cooling pipe 1 603b—hose 603d—cooling pipe 2 603c—water tank 501a.

[0050] The power member 604 includes an arc frame 604a, a connecting tube 604b, a rubber wheel 604c, a second spring 604d and a rubber strip 604e. The arc frame 604a is fixedly arranged on the top of the fixed frame 603e, the connecting tube 604b is sleeved and slidably arranged on the side of the arc frame 604a, the rubber wheel 604c is rotatably arranged on the bottom of the connecting tube 604b, the rubber wheel 604c is squeezed and rolled on the side of the hose 603d, the two ends of the second spring 604d are fixedly arranged on the inner side of the arc frame 604a and the side of the connecting tube 604b, and the rubber strip 604e is fixedly arranged on the side of the gear ring 601d. A plurality of rubber strips 604e are arranged and evenly spaced on the side of the gear ring 601d. When the rubber strips 604e rotate with the gear ring 601d, they roll with the rubber wheel 604c.

[0051] When in use: after the motor 501b rotates, the transmission device 601b drives the transmission shaft 601a to rotate, and the transmission shaft 601a drives the rubber ring 2 602d and the transmission gear 601c to rotate.

[0052] After the second rubber ring 602d rotates, it drives the first rubber ring 602c to rotate by friction, and the first rubber ring 602c drives the rotating shaft 602a to rotate, and the rotating shaft 602a drives each disturbance leaf 602b to rotate. After the disturbance leaf 602b rotates, it moves the hot air between the fins to speed up the discharge of the internal hot air, thereby improving the heat dissipation effect of the fin heat sink 400.

[0053] After the transmission gear 601c rotates, it drives the gear ring 601d to rotate, and after the gear ring 601d rotates, it drives the air supply member 601 and the power member 604. Driven by the gear ring 601d, the bevel gear 601f drives the air supply fan 601e to rotate, and the air supply fan 601e blows the air flow to the inside of the fins. Under the action of the air supply fan 601e, the air flow speed between the fins is accelerated, and the heat dissipation speed is accelerated, thereby increasing the heat dissipation effect of the fin heat sink 400.

[0054] After the gear ring 601d rotates, the rubber strip 604e rotates with it and contacts the rubber wheel 604c. Under the rolling and squeezing action of the rubber strip 604e, the rubber wheel 604c slides on the side of the arc frame 604a with the connecting tube 604b while squeezing the hose 603d. After the hose 603d is squeezed, the water inside it starts to flow, thus forming a partial circulation of cooling water. As the rubber strip 604e and the rubber wheel 604c are separated, the rubber wheel 604c is pulled back by the spring 2 604d, and then connected with the second rubber strip 604e, thus rolling and squeezing the hose 603d again. During the repeated squeezing of the rubber wheel 604c, the cooling water starts to flow in the cooling tube 1 603b and the cooling tube 2 603c, thereby being able to fully absorb the heat in the fins.

[0055] The remaining structure is the same as that of Example 2.
